Answer:
78 km/h
Step-by-step explanation:
Let s represent the speed of the slower car. The total speed of the two cars is their closing speed:
(s) + (s+14 km/h) = (340 km)/(2 h)
2s + 14 km/h = 170 km/h . . . . . simplify
s + 7 km/h = 85 km/h . . . . . . . . divide by 2
s = 78 km/h . . . . . . . . . . . . . . . . subtract 7 km/h
The rate of the slower car is 78 km/h.
